[0035] In the related art, a gripping structure is provided on the mobile phone protective case for the user to grip when playing games, so as to improve the gripping stability of the mobile phone when playing games. However, the gripping structure makes the back of the mobile phone protective case uneven, affecting the portability of the mobile phone.

[0036] The utility model provides a mobile device protection case, aiming to solve the technical problem of how to improve the use effect of the mobile device protection case in different use states of the mobile phone.

[0037] In the embodiment of the present utility model, Figure 1 and Figure 2 As shown, the mobile device protective case includes: a shell body 10, the shell body 10 includes a support plate 11 and a frame 12 connected to the periphery of the support plate 11, the support plate 11 and the frame 12 are arranged to form a protective groove, and the protective groove is used to accommodate the mobile device; a gripping piece 20, the gripping piece 20 is deformably installed on the side of the support plate 11 away from the protective groove, the gripping piece 20 has a flat shape and an arched shape that can be switched by deformation, in the flat shape, the gripping piece 20 is flat and close to the support plate 11; in the arched shape, the gripping piece 20 is partially arched relative to the support plate 11 for human hand holding; the number of the gripping pieces 20 is two, and the two gripping pieces 20 are distributed along the length direction of the shell body 10.

[0038] In this embodiment, the mobile device can be a mobile phone or a tablet computer. The mobile device protective shell is used to be set on the mobile device to protect the mobile device. The support plate 11 can be a plastic plate, and the frame 12 can be a hard plastic frame or a flexible plastic frame, which is not limited here. The specifications of the protective groove can be pre-designed according to the models of different mobile devices. The grip 20 is made of a soft material with a certain supporting force, which can be thermoplastic polyurethane (TPU) or thermoplastic elastomer (TPE), so that it can be freely deformed between the arched form and the flat form, and can maintain the shape in the arched form. When the grip 20 is in the arched form, the arched form can be maintained unchanged within the preset force range. When the user uses the mobile device to play games, the user's hands can grasp the two grips 20 respectively, wherein the user's thumb is used to touch the screen of the mobile device, and the user's other four fingers can be buckled on the grip 20, thereby increasing the grip area of ​​the user's hand on the mobile device protective shell, so as to improve the user's grip stability of the mobile device when playing games and improve the user experience. Of course, the arched grip 20 can also support the mobile device to stand in a horizontal position, making it convenient for users to watch videos hands-free.

[0039] When the grip 20 is in a flat state, the grip 20 is flat as a whole and close to the support plate 11, so that the back of the mobile device protective case can remain flat, thereby reducing the occupied space and making it convenient for users to store and carry the mobile device with the mobile device protective case.

[0040] Specifically, Figure 3 and Figure 4 As shown, the gripping member 20 has a connecting edge 21 and a movable edge 22 that are relatively arranged, the connecting edge 21 is positioned and connected to the shell body 10, and the movable edge 22 can be slidably connected to the shell body 10 to approach or move away from the connecting edge 21; the movable edge 22 has a first position away from the connecting edge 21, and a second position close to the connecting edge 21; when the movable edge 22 is in the first position, the gripping member 20 switches to the flat form; when the movable edge 22 is in the second position, the gripping member 20 switches to the arched form.

[0041] The position of the connecting edge 21 is fixed, while the movable edge 22 can move closer to or farther from the connecting edge 21 by sliding along the support plate 11, and the moving direction of the movable edge 22 is the length direction of the shell body 10. When the movable edge 22 approaches the connecting edge 21, the portion of the gripping member 20 between the movable edge 22 and the connecting edge 21 arches in a direction away from the support plate 11. When the movable edge 22 moves away from the connecting edge 21, the gripping member 20 is flat and close to the support plate 11.

[0042] The connecting edges 21 of the two grips 20 can be respectively close to the two ends of the support plate 11 along the length direction. When the movable edges 22 of the two grips 20 are in their respective first positions, the movable edges 22 of the two grips 20 are adjacent to each other side by side in the middle position of the support plate 11. When it is necessary to switch the grip 20 from a flat state to an arched state, the user can drive the movable edge 22 close to the connecting edge 21 so that the middle part of the grip 20 is deformed and arched after being subjected to force. When it is necessary to switch the grip 20 from an arched state to a flat state, the user can drive the movable edge 22 away from the connecting edge 21 so that the grip 20 returns to a flat state close to the support plate 11. By driving the connecting edge 21 to move to realize the switching deformation of the grip 20 between the flat state and the arched state, the shape switching process of the grip 20 can be made more convenient.

[0043] For example, Figures 3 to 5 As shown, the support plate 11 is provided with a slide groove 13, and the slide groove 13 extends along the sliding direction of the movable edge 22. The movable edge 22 is connected with a sliding member 30, and the hardness of the sliding member 30 is greater than the hardness of the holding member 20. The sliding member 30 is provided with a sliding portion 31 protruding from one side of the support plate 11, and the sliding portion 31 can be slidably matched with the slide groove 13.

[0044] Since the hardness of the sliding member 30 is greater than that of the gripping member 20, the sliding member 30 is less likely to deform when subjected to force, and can slide along the preset track. The sliding member 30 can drive the movable edge 22 to slide after receiving a driving force, so as to improve the sliding effect of the movable edge 22 under force. The sliding portion 31 is integrally formed with the sliding member 30, and the sliding portion 31 can slide along the slide groove 13, so that the sliding process of the sliding member 30 and the movable edge 22 is more stable.

[0045] Specifically, Figure 5 As shown, there are two slide grooves 13, and the two slide grooves 13 are arranged side by side; the sliding member 30 extends along the length direction of the movable edge 22, and the sliding parts 31 are protruding at both ends of the sliding member 30, and the two sliding parts 31 are slidably matched with the two slide grooves 13 respectively; the sliding part 31 partially protrudes from the end surface of the sliding member 30 along the length direction to form a limiting part 32; the groove wall of the slide groove 13 is provided with a limiting groove, and the limiting groove extends along the length direction of the slide groove 13, and the limiting part 32 is slidably matched with the limiting groove to limit the sliding part 31 from disengaging from the slide groove 13.

[0046] The number of the sliding parts 31 is set to two and they are respectively slidably matched with the two slide grooves 13, which can increase the matching area between the sliding part 30 and the support plate 11, improve the matching stability, and thus improve the sliding stability of the movable edge 22. The two limiting parts 32 protrude from the two end surfaces of the sliding part 30, respectively, and the two limiting parts 32 are respectively matched with the limiting grooves in each slide groove 13, so that the two ends of the sliding part 30 cannot be separated from the two slide grooves 13, so as to improve the matching structural stability of the sliding part 30 and the support plate 11.

[0047] For example, Figure 6 and Figure 7 As shown, a slot 33 is provided on the side of the sliding portion 31 away from the limiting portion 32, and the slot 33 has a first slot wall and a second slot wall arranged opposite to each other; the slot wall of the sliding slot 13 is convexly provided with a first convexity 14 corresponding to the first position, and a second convexity 15 corresponding to the second position; when the movable edge 22 is in the first position, the first slot wall abuts against the first convexity 14 to increase the resistance of the movable edge 22 when moving toward the second position; when the movable edge 22 is in the second position, the second slot wall abuts against the second convexity 15 to increase the resistance of the movable edge 22 when moving toward the first position.

[0048] When the movable edge 22 is in the first position, the sliding member 30 and the sliding portion 31 are also in the first position. At this time, the first groove wall of the slot 33 abuts against the first latch protrusion 14, which can position the sliding portion 31 in the first position to prevent the sliding portion 31 from easily leaving the first position, thereby positioning the sliding portion 31 and the movable edge 22 in the first position, so that the gripping member 20 can be stably maintained in a flat shape corresponding to the first position.

[0049] When the movable edge 22 is in the second position, the sliding member 30 and the sliding portion 31 are also in the second position. At this time, the second groove wall of the slot 33 abuts against the second latch protrusion 15, and the sliding portion 31 can be positioned in the second position to prevent the sliding portion 31 from easily leaving the second position, thereby positioning the sliding portion 31 and the movable edge 22 in the second position, so that the gripping member 20 can be stably maintained in the arched shape corresponding to the second position.

[0050] It can be understood that the resistance generated by the first latching protrusion 14 and the second latching protrusion 15 on the sliding part 31 should be a resistance that the user can overcome with his hands, so that when the user needs to switch the shape of the grip 20, the user can push the sliding part 30 from the first position to the second position, or from the second position to the first position.

[0051] Specifically, Figure 6 and Figure 7 As shown, the support plate 11 is provided with a first deformation groove 111 and a second deformation groove 112 adjacent to the slide groove 13, the first deformation groove 111 corresponds to the first position, and the second deformation groove 112 corresponds to the second position; the support plate 11 forms a first elastic arm 16 at a portion between the first deformation groove 111 and the slide groove 13, and forms a second elastic arm 17 at a portion between the second deformation groove 112 and the slide groove 13, the first latching protrusion 14 is protruded from the first elastic arm 16, and the second latching protrusion 15 is protruded from the second elastic arm 17.

[0052] When the user pushes the sliding portion 31 to squeeze the first protrusion 14, the force can be transmitted to the first elastic arm 16 to cause the first elastic arm 16 to bend and deform toward the first deformation groove 111, so that the sliding portion 31 can temporarily squeeze the first protrusion 14 out of the groove 33 to overcome the obstruction caused by the first protrusion 14 and then move toward the second position.

[0053] When the user pushes the sliding portion 31 to squeeze the second protrusion 15, the force can be transmitted to the second elastic arm 17 to cause the second elastic arm 17 to bend and deform toward the second deformation groove 112, so that the sliding portion 31 can temporarily squeeze the second protrusion 15 out of the groove 33 to overcome the obstruction caused by the second protrusion 15 and then move toward the first position.

[0054] Therefore, the first elastic arm 16 and the second elastic arm 17 can reduce the difficulty for the user to drive the sliding member 30 to overcome the resistance and leave the first position or the second position, so as to improve the convenience of switching the shape of the gripping member 20.

[0055] In practical applications, such as Figure 6 and Figure 7 As shown, a first guide slope 141 is formed on one side of the first locking protrusion 14 facing the second locking protrusion 15, and the first guide slope 141 is used for the sliding contact portion 31 to slide and abut when the sliding portion 31 moves to the first position, so as to guide the first locking protrusion 14 into the locking groove 33;

[0056] And / or, a second guide slope 151 is formed on one side of the second locking protrusion 15 facing the first locking protrusion 14 , and the second guide slope 151 is used for sliding abutment when the sliding portion 31 moves to the second position to guide the second locking protrusion 15 into the locking groove 33 .

[0057] When the user pushes the sliding portion 31, the direction of the force applied to the first locking protrusion 14 is perpendicular to the deformable direction of the first elastic arm 16. The first guiding inclined surface 141 can decompose the force applied to the first locking protrusion 14, thereby generating a component force that is consistent with the deformable direction of the first elastic arm 16. In this way, the component force can more easily squeeze and deform the first elastic arm 16, thereby reducing the difficulty for the user to overcome the obstacle of the first locking protrusion 14. In this way, compared with leaving the first position, the sliding portion 31 can more easily enter the first position and cooperate with the first locking protrusion 14 to stably stay in the first position.

[0058] When the user pushes the sliding portion 31, the direction of the force applied to the second locking protrusion 15 is perpendicular to the deformable direction of the second elastic arm 17. The second guiding inclined surface 151 can decompose the force applied to the second locking protrusion 15, thereby generating a component force that is consistent with the deformable direction of the second elastic arm 17. In this way, the component force can more easily squeeze and deform the second elastic arm 17, thereby reducing the difficulty for the user to overcome the obstruction of the second locking protrusion 15. In this way, compared with leaving the second position, the sliding portion 31 can more easily enter the second position and cooperate with the second locking protrusion 15 to stably stay in the second position.

[0059] For example, Figure 1 and Figure 8As shown, the sliding member 30 is provided with a hand-grip groove 34 on one side facing away from the support plate 11; and / or, the connecting edge 21 is rotatably connected to the support plate 11. The hand-grip groove 34 can be grasped by the user's fingertips to apply a driving force to the sliding member 31, thereby facilitating the user to apply force, so as to improve the convenience of the user to drive the movable edge 22. The connecting edge 21 is penetrated by a connecting shaft, and the two ends of the connecting shaft are rotatably matched with the connecting groove on the support plate 11, so that when the movable edge 22 slides between the first position and the second position, the connecting edge 21 can rotate in accordance with the deformation of the grip 20, so that the deformation process of the grip 20 can be more natural and smooth, avoiding the grip 20 from breaking after being bent multiple times by force near the connecting portion, and also reducing the resistance encountered by the movable edge 22 when it approaches the connecting edge 21.

[0060] Specifically, Figure 4 As shown, a recessed groove 18 is provided on one side of the support plate 11 away from the protective groove, and the holding piece 20 is laid in the recessed groove 18 when it is switched to the flat state; a limiting rib 181 is convexly provided on the groove wall at the notch of the recessed groove 18, and when the holding piece 20 is laid in the recessed groove 18, the limiting rib 181 abuts against a side of the holding piece 20 exposed in the recessed groove 18.

[0061] The gripping piece 20 is laid in the sink 18 in a flat state, so that the surface of the gripping piece 20 in the flat state can be kept flat with the back of the support plate 11, thereby improving the appearance integrity of the mobile device protective case when the gripping piece 20 is in the flat state. Since the gripping piece 20 is flexible and deformable, even in a flat state, due to the influence of its own material, the local position will be uneven and protrude from the notch of the sink 18. The limiting ribs 181 can crimp the gripping piece 20 in a flat state into the sink 18 to prevent the gripping piece 20 from protruding from the notch of the sink 18 due to local unevenness, thereby maintaining the shape stability of the mobile device protective case. There are multiple limiting ribs 181, and the multiple limiting ribs 181 are arranged at intervals along the periphery of the notch of the sink 18 to increase the limiting abutment area of ​​the gripping piece 20 and improve the shape retention effect of the gripping piece 20.

[0062] A mating groove corresponding to the limiting rib 181 can be provided on one side of the gripping piece 20 exposed from the notch of the sink 18. The limiting rib 181 cooperates with the mating groove so that the limiting rib 181 and the outer surface of the gripping piece 20 can form a whole flat surface, thereby improving the appearance integrity of the back of the protective case of the mobile device and improving the touch feel.

[0063] In practical applications, such as Figure 8As shown, a shaping piece 40 is provided on one side of the gripping member 20 facing the support plate 11, the hardness of the shaping piece 40 is greater than the hardness of the gripping member 20, the shaping piece 40 extends along the length direction of the movable edge 22, the number of the shaping pieces 40 is at least two and they are arranged at intervals along the movement direction of the movable edge 22; the gripping member 20 has a peak portion 23 in the arched form, and the shaping piece 40 is provided on at least one side of the peak portion 23. The number of shaping pieces 40 is positively correlated with the length of the gripping member 20, that is, the actual number of shaping pieces 40 can be adjusted according to the actual length of the gripping member 20, and is not limited here.

[0064] The shaping sheet 40 can be made of a material different from that of the grip 20, such as a metal sheet or a plastic sheet. After the grip 20 switches to the arched shape, the shaping sheet 40 can provide sufficient support for the grip 20, so that the grip 20 can be effectively maintained in the arched shape and will not easily collapse under the user's gripping force. The arch peak 23 is the part of the grip 20 that is farthest from the support plate 11 in the arched shape. The distance between the grip 20 and the support plate 11 in the arched shape gradually decreases from the arch peak 23 toward both ends. The shaping sheet 40 can be set on both sides of the arch peak 23. Of course, it can also be that the shaping sheet 40 is set on one side and the thickened part made of the same material as the grip 20 is set on the other side. Providing a shaping sheet 40 on at least one side of the arch peak 23 can effectively maintain the shape of the arch peak 23 and further improve the shape stability of the grip 20 in the arched shape.

[0065] In the technical solution of the protective case for a mobile device of the present invention, two gripping members 20 are arranged on the back of the case body 10, and the gripping members 20 can be deformed relative to the case body 10; when the gripping members 20 are switched to an arched shape, they can be grasped by the user's hand to improve the user's grip stability when playing games, and can also be used as a video stand to facilitate audio-visual entertainment and improve the user experience; when the gripping members 20 are switched to a flat shape, they can be flattened and placed close to the support plate 11 to achieve a storage effect, reduce occupied space, and facilitate user carrying.
